Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but unlikely to cause flood-related damage. The morning high tide is expected near 20.5 ft.
WHEN
Highest risk from approximately 6:00 AM to 8:00 AM PST.
IMPACTS
Minor flooding in very low-lying coastal areas is possible, but significant property damage is unlikely.
• Barometric pressure at the morning peak (around 1014 hPa) is higher than most severe flood events, reducing the chance of widespread flooding.
• NOAA’s Flood Likelihood is 7.2% for 2025-01-15, which is moderate but still below levels observed in more damaging historical Category 4 or 5 events.
• Winds are generally light and not from the W/NW, further lowering the risk of severe coastal inundation.
• This situation is comparable to past Category 3 events (e.g., 01/06/2025), which had similar tide heights but slightly higher NOAA flood likelihood.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. High tides are again near 20.4 ft, but damage is unlikely.
WHEN
Primary period of concern is from about 7:00 AM to 9:00 AM PST.
IMPACTS
Minor inundation of beaches or coastal walkways is possible, particularly around the morning high tide; however, broader property impacts are not expected.
• Barometric pressure remains relatively high (around 1023 hPa in the morning), limiting severe flood potential.
• NOAA’s Flood Likelihood is 4.2% for 2025-01-16, lower than Day 1, suggesting a lesser chance of flooding despite the similar tidal range.
• Historical data indicates that tides above 20 ft should be watched carefully, but high pressure and modest wind speeds reduce flooding risk to Category 3.
CATEGORY 3
WHAT
Close to a flood event with high tides around 20.2 ft, but still unlikely to cause major issues.
WHEN
Greatest risk window extends from roughly 7:30 AM to 9:30 AM PST.
IMPACTS
Potential for minor roadway or parking lot ponding near the coast, but widespread flooding is not anticipated.
• Barometric pressure is near 1019 hPa, which is not low enough to significantly amplify tidal flooding.
• NOAA’s Flood Likelihood is 2.8%, even lower than the previous two days.
• Despite the relatively high tide height, conditions are comparable to milder historical Category 3 events, with no strong onshore winds and moderate atmospheric pressure.
You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
